e44dec027c add release note about supporing non-TRUC <minrelay txns 2025-12-19 14:20:43 -05:00

1488315d76 policy: Allow any transaction version with < minrelay
Prior to cluster mempool, a policy was in place that
disallowed non-TRUC transactions from being
TX_RECONSIDERABLE in a package setting if it was below
minrelay. This was meant to simplify reasoning about mempool
trimming requirements with non-trivial transaction
topologies in the mempool. This is no longer a concern
post-cluster mempool, so this is relaxed.

In effect, this makes 0-value parent transactions relayable
through the network without the TRUC restrictions and
thus the anti-pinning protections.

Pull request description:

  [Reopening #28676 here as a new PR, because GitHub is slow to load the page making it hard to scroll through and see comments.  Also, that PR was originally opened with a prototype implementation which has changed significantly with the introduction of `TxGraph`.]

  This is an implementation of the [cluster mempool proposal](https://delvingbitcoin.org/t/an-overview-of-the-cluster-mempool-proposal/393).

  This branch implements the following observable behavior changes:

   - Maintains a partitioning of the mempool into connected clusters (via the `txgraph` class), which are limited in vsize to 101 kvB by default, and limited in count to 64 by default.
   - Each cluster is sorted ("linearized") to try to optimize for selecting highest-feerate-subsets of a cluster first
   - Transaction selection for mining is updated to use the cluster linearizations, selecting highest feerate "chunks" first for inclusion in a block template.
   - Mempool eviction is updated to use the cluster linearizations, selecting lowest feerate "chunks" first for removal.
   - The RBF rules are updated to: (a) drop the requirement that no new inputs are introduced; (b) change the feerate requirement to instead check that the feerate diagram of the mempool will strictly improve; (c) replace the direct conflicts limit with a directly-conflicting-clusters limit.
   - The CPFP carveout rule is eliminated (it doesn't make sense in a cluster-limited mempool)
   - The ancestor and descendant limits are no longer enforced.
   - New cluster count/cluster vsize limits are now enforced instead.
   - Transaction relay now uses chunk feerate comparisons to determine the order that newly received transactions are announced to peers.

  Additionally, the cached ancestor and descendant data are dropped from the mempool, along with the multi_index indices that were maintained to sort the mempool by ancestor and descendant feerates. For compatibility (eg with wallet behavior or RPCs exposing this), this information is now calculated dynamically instead.

f6ec3519a330e5c3899a4d9f7d26b7980a597b41 init: Require explicit -asmap filename (Ryan Ofsky)

Pull request description:

  Currently, if `-asmap` is specified without a filename bitcoind tries to load `ip_asn.map` data file.

  This change now requires `-asmap=ip_asn.map` or another filename to be specified explicitly.

  The change is intended to make behavior of the option explicit and avoid confusion reported https://github.com/bitcoin/bitcoin/issues/33386 where documentation specifies a default file which is not actually loaded by default. It was originally implemented in
  https://github.com/bitcoin/bitcoin/pull/33631#issuecomment-3410302383 and various alternatives are discussed there.

Merge bitcoin/bitcoin#33286: doc: update multisig tutorial to use multipath descriptors
de7c3587cd4586bbed94a4ea6eae4a252301daee doc: Update add checksum instructions in tutorial (Ben Westgate)
2a46e94a1600a4f28e01db23a89f039acaa2c45e doc: Update multisig-tutorial.md to use multipath descriptors (Ben Westgate)

Pull request description:

  ### Summary

  Update `doc/multisig-tutorial.md` to use multipath descriptor format
  instead of separate external/internal descriptors. The tutorial now:

  - extracts a single `xpub_n` per participant
  - constructs a multipath `wsh(sortedmulti(...))` descriptor with `<0;1>`
    change index semantics
  - uses `getdescriptorinfo` to compute descriptor checksum
  - explains that `importdescriptors` expands the multipath descriptor
    into internal and external descriptors
  - update `/test/functional/wallet_multisig_descriptor_psbt.py` functional test / documentation to use multi-path descriptors

  ---

  ### Motivation

  A single multipath descriptor is the most convenient pattern for multisig; our documentation should use it.

  ---

  ### What changed

  - replaced extraction of `external_xpub_n` and `internal_xpub_n` with
    extraction of a single `xpub_n`
  - removed instructions to create and import separate external/internal
    descriptors
  - added instructions to build a multipath `wsh(sortedmulti(...))`
    descriptor and derive checksum with `getdescriptorinfo`
  - checksum field is parsed and appended as the multipath descriptor is not the canonical "desc" output
  - clarified that `importdescriptors` automatically expands multipath
    descriptors into internal and external forms
  - similar changes to the functional test: wallet_multisig_descriptor_psbt.

  ---

  ### Testing

  I have run the updated shell snippets and confirmed the multipath descriptor produces the same `listdescriptors` output after importing as the two descriptor method in bitcoin:master.

  ---

  ### Related issues / PRs

  This tutorial change references the multipath descriptor
  consolidation (see commit / PR referenced in the change). The commit
  message points to bitcoin#22838 as the upstream change that enables
  this behavior.

  ---

  ### Release note (for changelog)

  Documentation: update multisig tutorial and multisig functional test to use multipath descriptors

Pull request description:

  This is a small follow-up for #32941 (commit 1384dbaf6d0bfcdb05f97e1e3cb3d5e498bee505), removing the `-maxorphantx` option completely, now that v30 has been released. If removing it for v31 is seen as controversial/premature (I personally don't think it is), the merge can be delayed for a future release.

Pull request description:

  Operating a Bitcoin node across multiple networks poses some fingerprinting risk. [0] Currently, this is not clear from the documentation and may be causing direct harm to users who are unaware of this.

  The included documentation change indicates this risk factor but also notes that operating a node across multiple networks does provide an important benefit (increases the cost of eclipse and partitioning attacks) and is thus not discouraged outright.

  The i2p documentation did not include a privacy recommendations section, so that is added as well.

f6ec3519a3 init: Require explicit -asmap filename
Currently, if `-asmap` is specified without a filename, bitcoind tries to load
`ip_asn.map` data file.

This change now requires `-asmap=ip_asn.map` or another filename to be
specified explicitly.

The change is intended to make behavior of the option explicit avoid confusion
reported https://github.com/bitcoin/bitcoin/issues/33386 where documentation
specifies a default file which is not actually loaded by default. It was
originally implemented in

Merge bitcoin/bitcoin#33555: build: Bump clang minimum supported version to 17

faed118fb30fbc303e9d4c70569abfee397f1759 build: Bump clang minimum supported version to 17 (MarcoFalke)

Pull request description:

  Most supported operating systems ship with clang-17 (or later), so bump the minimum to that and allow new code to drop workarounds for previous clang bugs.

  (Apart from dropping the small workaround, this bump allows the `ci_native_nowallet_libbitcoinkernel` CI to run on riscv64 without running into an ICE with clang-16.)

  This patch will only be released in version 31.x, next year (2026).

  For reference:

  * https://packages.debian.org/bookworm/clang-19
  * https://packages.ubuntu.com/noble/clang (clang-18)
  * CentOS-like 8/9/10 ship clang-17 (and later) via Stream
  * FreeBSD 12/13 ship clang-17 (and later) via packages
  * OpenSuse Tumbleweed ships with https://software.opensuse.org/package/clang (clang21); No idea about OpenSuse Leap

  On operating systems where the clang version is not shipped by default, the user would have to use GCC, or install clang in a different way. For example:

  * https://packages.debian.org/bookworm/g++ (g++-12)
  * https://packages.ubuntu.com/jammy/g++ (g++-11)
  * https://apt.llvm.org/, or nix, or guix, or compile clang from source, ...

  *Ubuntu 22.04 LTS does not ship with clang-16 (the previous minimum required), nor with clang-17, so one of the above workarounds is needed there.*

  macOS 14 is unaffected, and the previous minimum requirement of Xcode15.0 remains, see also 919e6d01e9/depends/hosts/darwin.mk (L3-L4). (Modulo compiling the fuzz tests, which requires 919e6d01e9/.github/workflows/ci.yml (L149))

Pull request description:

  The main goal is to remove [deprecated](https://github.com/bitcoin/bitcoin/issues/32361) code (removed in C++26).

  This PR employs Microsoft's modern [approach](https://learn.microsoft.com/en-us/windows/apps/design/globalizing/use-utf8-code-page) to handling UTF-8:
  > Until recently, Windows has emphasized "Unicode" -W variants over -A APIs. However, recent releases have used the ANSI code page and -A APIs as a means to introduce UTF-8 support to apps. If the ANSI code page is configured for UTF-8, then -A APIs typically operate in UTF-8. This model has the benefit of supporting existing code built with -A APIs without any code changes.

  TODO:
  - [x] Handle application manifests properly when building with MSVC.
  - [x] Bump the minimum supported Windows version to 1903 (May 2019 Update).
  - [x] Remove all remaining use cases of the deprecated `std:wstring_convert`.
      - The instance in `subprocess.h` will be addressed in a follow-up PR, as additional tests are likely needed.
      - The usage in `common/system.cpp` is handled in https://github.com/bitcoin/bitcoin/pull/32566.

  Resolves partially https://github.com/bitcoin/bitcoin/issues/32361.

  <!--
  Please provide clear motivation for your patch and explain how it improves
  Bitcoin Core user experience or Bitcoin Core developer experience
  significantly:

  * Any test improvements or new tests that improve coverage are always welcome.
  * All other changes should have accompanying unit tests (see `src/test/`) or
    functional tests (see `test/`). Contributors should note which tests cover
    modified code. If no tests exist for a region of modified code, new tests
    should accompany the change.
  * Bug fixes are most welcome when they come with steps to reproduce or an
    explanation of the potential issue as well as reasoning for the way the bug
    was fixed.
  * Features are welcome, but might be rejected due to design or scope issues.
    If a feature is based on a lot of dependencies, contributors should first
    consider building the system outside of Bitcoin Core, if possible.
  * Refactoring changes are only accepted if they are required for a feature or
    bug fix or otherwise improve developer experience significantly. For example,
    most "code style" refactoring changes require a thorough explanation why they
    are useful, what downsides they have and why they *significantly* improve
    developer experience or avoid serious programming bugs. Note that code style
    is often a subjective matter. Unless they are explicitly mentioned to be
    preferred in the [developer notes](/doc/developer-notes.md), stylistic code
    changes are usually rejected.

  Bitcoin Core has a thorough review process and even the most trivial change

Pull request description:

  ### Background

  As part of the release process we often run *contrib/devtools/headerssync-params.py* and increase the values of the constants `HEADER_COMMITMENT_PERIOD` and `REDOWNLOAD_BUFFER_SIZE` in *src/headerssync.cpp* as per *doc/release-process.md* (example: 11a2d3a63e90cdc1920ede3c67d52a9c72860e6b). This helps fine tune the memory consumption per `HeadersSyncState`-instance in the face of malicious peers.

  (The `REDOWNLOAD_BUFFER_SIZE`/`HEADER_COMMITMENT_PERIOD` ratio determines how many Headers Sync commitment bits must match between PRESYNC & REDOWNLOAD phases before we start permanently storing headers from a peer. For more details see comments in *src/headerssync.h* and *contrib/devtools/headerssync-params.py*).

  ### Problem: Not feeding back headers until completing sync

  During v30 release process #33274 made `REDOWNLOAD_BUFFER_SIZE` exceed the `target_blocks` constant used to control the length of chains generated for testing Headers Sync (`15000`, *headers_sync_chainwork_tests.cpp*).

  The `HeadersSyncState::m_redownloaded_headers`-buffer now does not reach the `REDOWNLOAD_BUFFER_SIZE`-threshold during those unit tests. As a consequence `HeadersSyncState::PopHeadersReadyForAcceptance()` will not start feeding back headers until the PoW threshold has been met. While this will not cause the unit test to start failing on master, it means we have gone from testing behavior that resembles mainnet (way more than `REDOWNLOAD_BUFFER_SIZE` headers to reach the PoW limit), to behavior that is not possible/expected there.

  ### Solution

  Avoid testing this unrealistic condition of completing Headers Sync before reaching `REDOWNLOAD_BUFFER_SIZE` by making tests able to define their own values through the new `HeadersSyncParams` instead of having them hard-coded for all chains & tests.

  ### Commits

  * First 6 commits refactor and improve the unit tests in order to clarify latter changes.
  * We then add checks for the behavior around the `REDOWNLOAD_BUFFER_SIZE` threshold.
  * The main change: we extract the section from *headerssync.cpp* containing the constants to *kernel/chainparams.cpp*, making `HeadersSyncState` no longer hard-coded to mainnet.

  ### Notes

  This PR used to be called "headerssync: Preempt unrealistic unit test behavior".

fadad7a49477cd61fbbfe20a0a61023c2d4d70a1 Drop support for EOL macOS 13 (MarcoFalke)

Pull request description:

  Now that macOS 13 is EOL (https://en.wikipedia.org/wiki/MacOS_Ventura), it seems odd to still support it.

  (macOS Ventura 13.7.8 received its final security update on 20 Aug 2025: https://support.apple.com/en-us/100100)

  This patch will only be released in version 31.x, another 6 months out from now.

  So:

  * Update the depends build and release note template to drop EOL macOS 13.
  * As a result, update the earliest Xcode to version 16 in CI.
  * Also, bump the macOS CI runner to version 15, to avoid issues when version 14 will be at its EOL in about 1 year.

  This also allows to drop a small workaround in the fuzz tests and unlocks libcpp hardening (https://github.com/bitcoin/bitcoin/pull/33462)

fbde8d9a81 doc: remove unrelated bitcoin-wallet binary from libbitcoin_ipc description
`bitcoin-wallet` as-is is merely an offline wallet inspection tool
(introduced more than 9 years ago in PR #13926) that doesn't have any
relation with IPC/multiprocess, so remove it from the list of binaries
that use `libbitcoin_ipc`.

headerssync: Make HeadersSyncState more flexible and move constants
Move calculated constants from the top of src/headerssync.cpp into src/kernel/chainparams.cpp.

Instead of being hardcoded to mainnet parameters, HeadersSyncState can now vary depending on chain or test. (This means we can reset TARGET_BLOCKS back to the nice round number of 15'000).

Signet and testnets got new HeadersSyncParams constants through temporarily altering headerssync-params.py with corresponding GENESIS_TIME and MINCHAINWORK_HEADERS (based off defaultAssumeValid block height comments, corresponding to nMinimumChainWork). Regtest doesn't have a default assume valid block height, so the values are copied from Testnet 4. Since the constants only affect memory usage, and have very low impact unless dealing with a largely malicious chain, it's not that critical to keep updating them for non-mainnet chains.

GENESIS_TIMEs (UTC):
Testnet3: 1296688602 = datetime(2011, 2, 2)
Testnet4: 1714777860 = datetime(2024, 5, 3)
Signet: 1598918400 = datetime(2020, 9, 1)

Pull request description:

  Closes https://github.com/bitcoin/bitcoin/issues/26362

  This continues the work that was started with #26426. It fixes the overflow issue by switching the tracked values that are in danger of overflowing from `CAmount` to `arith_uint256`.

  The current approach opts for a simple solution to ensure compatibility with datadirs including the previous version of the index: The new version of the index goes into a separate location in the datadir (`index/coinstatsindex/` rather than `index/coinstats/` before, the new naming is more consistent with the naming of the other indexes). There is no explicit concept of versioning of the index which earlier versions of this PR had. Having the two different versions of the index in separate places allows for downgrading of the node without having to rebuild the index. However, there will be a warning printed in the logs if the new code (v30) detects the old index still being present. A future version could delete a left-over legacy index automatically.

  The PR also includes several minor improvements but most notably it lets new entries be calculated and stored without needing to read any DB records.

index: Fix coinstatsindex overflow issue
The index originally stored cumulative values in a CAmount type but this allowed for
potential overflow issues which were observed on Signet. Fix this by
storing the values that are in danger of overflowing in a arith_uint256.

Also turns an unnecessary copy into a reference in RevertBlock and
CustomAppend and gets
rid of the explicit total unspendable tracking which can be calculated
by adding the four categories of unspendables together.
